Is the water hardness level in Merrimack County likely to affect sensitive skin?
A common misconception is that any measurement of hardness in local water means it will cause skin irritation or dryness. However, government sampling in Merrimack County’s aquifer 112SRFD found a median hardness of 38.85 mg/L of calcium and magnesium combined, with recorded values ranging from 14.6 to 43.4 mg/L. None of these results exceed federal thresholds. This range indicates moderate hardness overall, which can affect water feel but does not directly diagnose sensitive skin issues. Each household should consider its specific water conditions to understand how hardness may influence skin comfort.
How do factors like sample and well depth influence what I should expect in my water?
The U.S. Geological Survey data comes from wells between 28 and 49 feet deep in the Merrimack County aquifer. Water characteristics like mineral content can vary depending on the depth and location of a well. Shallower or deeper wells in your area might have slightly different hardness or mineral profiles, meaning your home's water quality could differ from these samples. Since these figures represent an area-wide measure, testing your own water is essential to determine how these variations might impact sensitive skin in your household.
Does the age and material of plumbing affect water’s impact on sensitive skin?
Yes. Independent of the source water, plumbing materials and their age can influence skin comfort. Older pipes or certain materials can cause changes in water chemistry after it leaves the well or municipal system, possibly leading to skin irritation in sensitive individuals. Addressing these plumbing factors along with water quality can be important for creating the best water conditions for sensitive skin in your home.
What does the number of samples and wells tell me about the reliability of the Merrimack County water data?
The data includes six individual samples from three different wells taken over an eight-year span, from 2011 to 2019. While this provides a useful snapshot of the area’s aquifer 112SRFD water hardness characteristics, it is a limited dataset. Small sample sizes mean the figures represent general trends rather than exact levels at any single location or time. For a household concerned about sensitive skin, local testing remains the most accurate method to understand personal water conditions.
How should I interpret the measured range of hardness relative to federal standards?
The samples all measured below federal hardness thresholds, indicating compliance with aesthetic secondary standards. These standards relate to taste, staining, or corrosivity rather than health risks. Detection at these levels does not indicate unsafe water. Instead, it means the water is within expected mineral levels for the area. Households with sensitive skin can consider this baseline when evaluating treatment options but should not equate these detections with health concerns.
In summary, area-wide data on water hardness in Merrimack County’s aquifer provides useful context but should not be taken as a definitive assessment of your home’s water or its effect on sensitive skin. Testing your water source directly will reveal your specific mineral levels and help clarify whether they contribute to skin sensitivity.

Source: USGS groundwater sampling. Sampled 2019-10-08. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
